Skatepark Advisory Committee
The Core Group and the Skatepark Advisory Committee may seem identical, but they’re not. They are separate groups and have different tasks, but they will meet regularly.

 Core Group

This group is comprised of local skaters and those that have no reservations about the skatepark mission. The core group is the engine that powers the entire skatepark movement.

 Skatepark Advisory Committee

This group is an assembly of members representing other organizations. The SAC has representatives from the Core Group, the City, and other municipal and civic organizations. The SAC can be thought of as the director or navigator for the Core Group’s activities.

Just some more reading of the development guide 

this where we’re gonna have to have our interpersonal relationships to take root
